Angular And Energy Dependence Of Cross Sections For Ejection Of Electrons From Water Vapor. I. 50-2000-Ev Electron Impact, M. A. Bolorizadeh, M. Eugene Rudd

M. Eugene Rudd Publications

We have measured the angular and energy distribution of the absolute cross sections for ejection of electrons from water vapor by electrons incident at 50-2000 eV. The angular range was 15° to 150° and the range of secondary electron energies was from 2 eV to an energy equal to the primary energy minus the first ionization potential. Electron energies were analyzed with a parallel-plate electrostatic analyzer with a resolution of 1.1%. Generally good agreement is obtained with the data of Opal et al. [J. Chem. Phys. 55, 4100 (1971)l at 500 eV except at the extremes of their angular range. …

A Semantic Basis For Parallel Algorithm Design, Roger E. Eggen

Doctoral Dissertations

"As computing demands increase, emphasis is being placed on parallel architectures- To efficiently use parallel machines, software must be designed to take advantage of these machines. This research concentrates on an abstraction of algorithm design to permit the expression of parallel programs. The abstraction emphasizes thought about algorithms at a high level as opposed to algorithm implementation at a statement level. A model based on data flow allows algorithm expression using flow diagrams. The model specifies operating system requirements that support parallel programming at a module level. Paths are used to carry data between modules. Data enter modules through ports. …

A Computerized Audio-Visual Speech Model, Joaquin Alberto Vila Ruiz

Masters Theses

"This thesis describes an expert system able to animate (graphically) and reproduce (acoustically) a text in any language which uses the Latin alphabet. A rule editor has been developed to create and modify the set of letter-to-sound rules of the target language. A parser has been implemented to apply the set of rules and translate text-to-speech. Each phoneme has a unique sound and thus requires its particular positioning of the vocal organs which are displayed in two different projections: a front view and a profile cross view of a human face in synchronization with the output sounds of the speech …

Origin And Stratigraphy Of Holocene Sediments, Souris And Des Lacs Glacial-Lake Spillways, North-Central North Dakota, William M. Boettger

Theses and Dissertations

In the past few years, a new interpretation of the formation of the Souris and Des Lacs glacial-lake spillways has been proposed. Now, based on geomorphological evidence, it is concluded that the Souris and Des Lacs Valleys were formed by massive glacial-lake outburst floods at the end of the late Wisconsinan deglaciation. Five phases of drainage have been recognized with the first forming the Des Lacs Valley and the other four associated with drainage in the Souris Valley from different proglacial lakes in Canada. The last of these floods down the Souris Valley was the most erosive.

This study is …

Aggressive Behavior Of Mississippi Kites In Suburban Areas, Berkeley R. Peterson, Charles S. Brown

Great Plains Wildlife Damage Control Workshop Proceedings

The Mississippi Kite is a small diurnal bird of prey which nests throughout the southern Great Plains Its aggressive behavior during nesting has created problems for residents in suburban areas. The removal of the nest and relocation of the eggs and young will end the attacks by the parent birds. The eggs are incubated and the resulting young, as well as other young removed from problem nests, are then placed in foster nests in more remote areas. Preliminary results indicated this will be a very successful way of dealing with the young of problem kites and is an effective way …

Deer Damage Prevention Efforts In Pennsylvania, Jack M. Payee, William L. Palmer

Great Plains Wildlife Damage Control Workshop Proceedings

Research at the Pennsylvania State University was directed towards finding effective repellents to control damage caused by white-tailed deer (Odocoileus virginianus) and to develop a low-cost alternative to the traditional 2.4 m woven wire barrier fence, considered to be deer-proof, but too expensive for mgt agricultural uses. Fourteen repellents were screened and 9 were found to be more effective than the others. These 9 repellents were further investigated under semi-field conditions and only 1 repellent was found to be consistent in reducing deer feeding. A vertical electric deer fence was effective in excluding deer at field sites containing alfalfa, small …

Investigation Of Electronic Holography Using Spice Computer Simulation Experiments, Monish Ranjan Chatterjee

Electrical and Computer Engineering Faculty Publications

Using SPICE experiments, it has been possible to verify most of the important aspects of electronic holography. The generation and properties of dynamic echoes under different types of nonlinearities have been extensively tested, and some new information has been garnered in the process. The case of pulse and generalized memory echoes has also been tested, and the results have been fairly satisfactory. Most of all, the simplicity with which the intriguing concept of memory echoes has translated into the circuit implementation on SPICE, and the closeness of the results to predicted behavior have been somewhat of a pleasant surprise.

Interactive Modification Of Quadratic Multiobjective Water Resources Planning Strategies, Paul J. Killian, Richard C. Peralta

Arkansas Water Resources Center Technical Reports

An interactive method is presented for modifying a compromise solution to a multiobjective water resources planning stategy by changing constraining conditions on regional objectives and local variables. The method is illustrated by modifying a bicriterion, sustained groundwater withdrawal strategy for minimizing the cost of meeting regional water demand on the Arkansas Grand Prairie. The strategy was developed using a model in which the finite difference form of the two-dimensional groundwater flow equation is embedded in an optimization process. The quadratic optimization is accomplished by utilizing the General Differential Algorithm to obtain values of the drawdown, pumping rate, and recharge rate …

The direct memory acquisition circuitry was developed in several stages and required both hardware and software development. An erasable programmable read only memory (EPROM) programmer was built for reading and loading the system program. The design, construction, and testing of the DMAC system are discussed in detail and an example of the use of this system for collecting data is given.

The Use Of Electrical Resistivity To Delineate A Brine Contamination Plume In The Walker Oilfield, Kent County, Michigan, Kent E. Meisel

Masters Theses

Contamination of groundwater with oil field brines was reported in the Walker Oil Field, Michigan. An electrical resistivity survey utilizing the Vertical Electrical Sounding method was conducted to test the method as an exploratory tool for delineating brine contamination in glacial deposits. The method was successful in defining the subsurface geology and delineating a shallow, confined aquifer, but the presence of extensive, conductive clays effectively masked the presence of brine contamination. The method was shown to be an effective exploratory tool for shallow investigations.
